Dell PowerStore Importing External Storage to PowerStore Guide

CHAP restrictions

The following describes the CHAP support for importing external storage to a PowerStore cluster:

• For Dell Unity and VNX2 systems, source volumes with single CHAP can be imported, source volumes with mutual CHAP cannot be imported.
• For Dell EqualLogic Peer Storage (PS) series, there are three cases:
  • When Discovery CHAP is disabled, source volumes with both single and mutual CHAP can be imported.
  • If Discovery CHAP is enabled, source volumes with single CHAP can be imported.
  • If Discovery CHAP is enabled, source volumes with mutual CHAP cannot be imported.
  NOTE:If Dell Unity or VNX2 systems are added in CHAP enabled mode and if a Dell EqualLogic PS system is added, ensure that Discovery CHAP is enabled for the Dell EqualLogic PS system.
• For Dell Compellent Storage Center (SC) series, source volumes with both single and mutual CHAP can be imported.
• Each host must be added with unique CHAP credentials.
